- menu: add runtime set-checked path (MenuItem::set_checked/clear_checked,
Menu::set_item_checked recursive, MenuBar::set_item_checked)
- dock: Split now stores per-child ratios (sum 1.0) so 3+ panels on one
axis keep distinct sizes; resize_split_child adjusts a single boundary,
resize_split keeps its two-arg whole-share semantics; one handle per
boundary; DockLayoutState VERSION bumped to 2 for the new ratios field
- audio_meter: MeterOrientation::Vertical for the 26px transport strip,
segments lit bottom to top
- viewer: ViewerFrameSource::CpuFrame + set_cpu_frame (BGRA8 RenderImage
via the sprite atlas) for platforms without CVPixelBuffer
- timeline: TimeDisplay::TimecodeDropFrame (SMPTE drop-frame for NTSC
rates, non-drop fallback otherwise)
- gpui_widgets: regression test pinning the fractional spacing helpers
(py_0p5/py_1p5/py_2p5/py_3p5 already exist; no _0_5 aliases added)
Adds interaction/render tests for the untested view layers: menu bar popup
open/click/keyboard-nav/escape, project explorer expand/open/view-switch,
scope widgets and keyable diamond rendering in windows, progress and file
dialog content rendering, and viewer transport buttons. gpui_widgets line
coverage rises from 75.4% to 89.4% (menu/mod 3.7%->71.9%, project_explorer
21.4%->91.3%, scopes/mod 0%->96.7%, keyable 69%->98.4%); every module is now
>=70%. 115 widget tests pass.
Two changes landing W4 of the oak task list:
gpui_macos: the Surface renderer only accepted biplanar YUV 4:2:0 pixel
buffers, so engine BGRA frames could not be displayed. SurfaceBounds gains an
is_bgra flag and draw_surfaces now creates a single BGRA8Unorm texture (and
the fragment shader swizzles it to RGBA) for 32BGRA buffers, keeping the
YUV path unchanged. Verified by running the W3 surface_bridge demo.
gpui_widgets::viewer: ViewerWidget with a pure TransportState machine
(advance/loop/step/in-out, unit-tested), a PlaybackClock trait the host
implements over the engine, a ~60Hz polling ticker, a transport bar emitting
ViewerEvent requests, timecode via gpui::timeline::time, and safe-frame/zoom
toggles. examples/viewer.rs shows a mock clock with generated macOS test
frames. 87 widget + 182 gpui tests pass.
